cmdserver: mask return code of runcommand in the same way as dispatch.run

"hg help" does not state that the code for abort is 255, but it's confusing
to have different code between hg command and command server.

Tests of python-hglib 1.2 passed with this change.

  $ hg init

Setup:

  $ echo a >> a
  $ hg ci -Am 'base'
  adding a

Refuse to amend public csets:

  $ hg phase -r . -p
  $ hg ci --amend
  abort: cannot amend public changesets
  [255]
  $ hg phase -r . -f -d

  $ echo a >> a
  $ hg ci -Am 'base1'

Nothing to amend:

  $ hg ci --amend
  nothing changed

  $ hg log -r . --template "{file_copies}\n"
  

Can't rollback an amend:

  $ hg rollback
  no rollback information available
  [1]

Preserve extra dict (issue3430):

  $ hg branch a
  marked working directory as branch a
  (branches are permanent and global, did you want a bookmark?)
  $ echo a >> a
  $ hg ci -ma
  $ hg ci --amend -m "a'"
  saved backup bundle to $TESTTMP/.hg/strip-backup/3837aa2a2fdb-amend-backup.hg (glob)
  $ hg log -r . --template "{branch}\n"

  saved backup bundle to $TESTTMP/.hg/strip-backup/c05c06be7514-amend-backup.hg (glob)
  $ hg log -r . --template "{branch}\n"
  a

Also preserve other entries in the dict that are in the old commit,
first graft something so there's an additional entry:

  $ hg up 0 -q
  $ echo z > z
  $ hg ci -Am 'fork'
  adding z
  created new head
  $ hg up 11
  5 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg graft 12
  grafting revision 12
  $ hg ci --amend -m 'graft amend'
  saved backup bundle to $TESTTMP/.hg/strip-backup/bd010aea3f39-amend-backup.hg (glob)
  $ hg log -r . --debug | grep extra
  extra:       amend_source=bd010aea3f39f3fb2a2f884b9ccb0471cd77398e
  extra:       branch=a
  extra:       source=2647734878ef0236dda712fae9c1651cf694ea8a

Preserve phase

  $ hg phase '.^::.'
  11: draft
  13: draft
  $ hg phase --secret --force .
  $ hg phase '.^::.'
  11: draft
  13: secret

Issue 3445: amending with --close-branch a commit that created a new head should fail
This shouldn't be possible:

  $ hg up -q default
  $ hg branch closewithamend
  marked working directory as branch closewithamend
  (branches are permanent and global, did you want a bookmark?)
  $ hg add obs.py
  $ hg ci -m..
  $ hg ci --amend --close-branch -m 'closing'
  abort: can only close branch heads
  [255]

This silliness fails:

  $ hg branch silliness
  marked working directory as branch silliness
  (branches are permanent and global, did you want a bookmark?)
  $ echo b >> b
  $ hg ci --close-branch -m'open and close'
  abort: can only close branch heads
